Abstract
A pipe coupling, wherein a pipe is freely insertable into the coupling and a nut causes engagement of a grip ring and gasket with the pipe to provide a seal between the coupling and the pipe, having a stop disposed therein to indicate to a user that the pipe has been inserted to a first position. Further tightening of the nut causes the pipe to move further into the coupling to a second position beyond the stop.
